GitHub - octanejs/octane: React’s programming model, compiled. The successor to Inferno, carrying its performance-first goal forward:
Octane is a fast JavaScript UI framework, and the successor to Inferno. You write components with the React API you already know, and a compiler turns them into direct DOM code before they ship. No virtual DOM, no rules-of-hooks bookkeeping, and no dependency arrays to maintain by hand. Created by Dominic Gannaway, who also created Inferno and has worked on React, Lexical, Ripple, and Svelte. Your
GitHub - Shakya47/pip-it-up: Pop any UI component into a floating Picture-in-Picture window. Zero config. Auto-sizing. Framework-agnostic core.
Status: Active Beta — The API is in active development and subject to change before v1.0. See the roadmap for upcoming features. The ultimate toolkit for the Document Picture-in-Picture API. Build highly interactive, tear-away windows for your web applications with native DOM moving, styling synchronization, and graceful fallbacks. pip-it-up is a framework-agnostic solution that makes it easy to o
React Native 0.84 - Hermes V1 by Default · React Native
Today we're excited to release React Native 0.84! This release makes Hermes V1 the default JavaScript engine, bringing significant performance improvements to all React Native apps. We've also continued removing the Legacy Architecture on both iOS and Android, and are shipping precompiled iOS binaries by default.

Introducing: React Best Practices - Vercel
We've encapsulated 10+ years of React and Next.js optimization knowledge into react-best-practices, a structured repository optimized for AI agents and LLMs. React performance work is usually, well, reactive. A release goes out, the app feels slower, and the team starts chasing symptoms. That’s expensive, and it’s easy to optimize the wrong thing. We’ve seen the same root causes across production
🎉 Ant Design 6.0 is Here! 🎉 · Issue #55804 · ant-design/ant-design

These numbers not only represent the community's activity and support but also witness the project's continuous evolution and maturation. It is because of you that Ant Design can continu
DeepIntoDev | In-Depth Software Development Insights
In the world of software development, filled with frameworks, libraries, and abstractions, I often felt like I was just using technologies without truly understanding them. So, I started digging deeper, reading more, and researching. That’s why I created this blog: to break down complex programming concepts into simpler, easy-to-understand explanations. DeepIntoDev is the place where you can under
Accelerating Large-Scale Test Migration with LLMs
By: Charles Covey-Brandt Airbnb recently completed our first large-scale, LLM-driven code migration, updating nearly 3.5K React component test files from Enzyme to use React Testing Library (RTL) instead. We’d originally estimated this would take 1.5 years of engineering time to do by hand, but — using a combination of frontier models and robust automation — we finished the entire migration in jus

ソースコードを解析して社内向けUIライブラリの使用状況を自動で集計する
デザインエンジニアの安田（@_yuheiy）です。 この記事では、社内向けに提供しているライブラリの使用状況を把握すべく作成した、プロダクト全体のソースコードを解析して、提供しているモジュールおよびそれを使用しているプロダクトごとに個別に自動集計する仕組みとその実装方法について解説します。 ライブラリ開発の問題と使用状況の解析 弊社では、KARTEのプロダクト群全体のデザインシステムである「Sour」を開発しています。その一環として、React製のUIライブラリ「sour-react」を作成し、社内向けのnpmパッケージとして提供しています。現在、sour-reactはKARTEのいくつものプロダクトにおいて採用されており、UI開発に欠かせないものになるほど浸透しています。 作成したライブラリが広く使われるようになるのは喜ばしくもありますが、一方、それに伴って新たな問題が生じることもありま

TanStack Router（& Query）はSPA開発で求めていたものだった✨【Reactのルーティングとデータ取得】
Reactの技術選定においてルーティングとデータ取得は特に重要な役割を担っています。 もちろんNext.jsやRemixのようなフレームワークを採用すれば、個別のライブラリを追加することなくルーティングからデータ取得までフレームワークが提供するAPIを使って実装することができます。 しかし、AI ShiftのようなBtoBのサービスにおいてはSPAで十分なことがほとんどで、Next.jsなどのフレームワークの採用がtoo muchになりかねません。 この記事は2024年2月時点の技術選定において、TanStack RouterがSPAのルーティングライブラリとして非常に有力な候補であることを紹介します。 はじめに TanStack RouterとTanStack Queryの採用がSPAアプリケーションにおける最適解の一つになりうることをその特徴と実際の設計例をもとに解説します。 TanS
